The genus, which is quite large, reaches its greatest develop- 

 ment in the tropics of the Old World, and there is only one 

 species in the western hemisphere, which may have been in- 

 troduced in the old days of the slave trade. Most of the species 

 are mimics and the strange thing is that the mimicking form 

 is generally the female, which has the color a.**A markings of 

 some one or other of the milkweed butterflie" ~~ the African 

 and oriental tropics. The female of our species patterns after 

 the markings of Danais chrysippus, a common milkweed but- 

 terfly of Africa. This adaptation of species t~ *^e form and 

 color of "protected" insects is of course not con&**nzs. It is the 

 result of a long evolution in past ages.
